The feeling or experience after the evolution of earth science needs more than 1500 words.

Part I: Reflections on Earth Science Reading.

The book Earth Science has four chapters and consists of fourteen lessons. My favorite is the third chapter "Weather on Earth". There are three lessons in this chapter: the first lesson is weather, and the second lesson is water cycle. The third lesson is to describe the weather.

I like the first lesson because it says "the four layers of the earth still exist in the atmosphere". These four layers are troposphere, stratosphere, mesosphere and thermosphere.

The troposphere is the closest layer to the earth, where clouds, rain, snow and lightning all occur.

In the stratosphere, the air is not static. A strong wind called "Rapids" blew on this floor.

The middle layer is located between the thermosphere and the advection layer.

The thermosphere is the uppermost layer of the atmosphere, where an optical phenomenon called "aurora" will appear.

I want to be a scientist when I grow up and help my country find more scientific treasures!

Part II: Reflections on Earth Science 1

After reading this book, I suddenly understood a lot of knowledge. In fact, some of our understandings are wrong, such as: the earth is not round at all, but pear-shaped; The sun is not sunrise or sunset at all, but an illusion when the earth turns from west to east, because the sun is motionless.

I also know the nine planets of the Milky Way: Venus, Jupiter, Mercury, Mars, Saturn, Earthstar, Uranus, Neptune and Pluto, and I read Yuan Zicheng's thoughts of Earth Science 1. Let me tell you the story of bison! Once upon a time, there were many bison in America, but people hunted them in large numbers for food and fur. Many people even kill bison just for fun. By 1900, bison had disappeared. William. Hornaday wants to save bison. 1905, he initiated the establishment of the American Bison Association, dedicated to restoring the bison herd. Today, bison live in the wild again, and people are still trying to save them.

I not only know that the sun is a star, but also know that it has a high temperature of tens of thousands of degrees. Every day we see the sun as if it were in air movement, but in fact it is not the sun that moves, but our earth revolves around it. The earth is also spinning. Every time it rotates, we have a day and a night. We must never observe the sun directly with our eyes, but we must observe the sun with a solar filter.

Next, let me introduce the moon! We can see the moon at night. Sometimes, in the daytime sky, we can also see the moon. The moon itself does not shine, but the sun illuminates it. The moon goes around the earth. With the revolution of the moon, its shape looks constantly changing. In about twenty-nine days, we can see the same change process. The moon was narrow at first, then it became wider and wider until it became round, and then it became narrower and narrower.

How's it going? Isn't it amazing? There is more knowledge waiting for you to discover!

Part III: Reflection on Earth Science II.

This book is extremely rich in knowledge, which makes me know a lot of knowledge. After reading Earth Science 2, I feel Yuan Zicheng.

I know the characteristics of the eight planets in the solar system. Venus: Venus is covered with thick yellow clouds. These clouds block the heat from the sun, making Venus the hottest planet. Jupiter: Jupiter is the largest planet in the solar system. It has a thick atmosphere and many rings made of dust. According to scientists' observation, Jupiter has sixty-four satellites. Mercury: Mercury is the closest planet to the sun. It is made of rock. Like the moon, there are many craters on the surface of Mercury. Mars: The surface of Mars is made of rocks and is red. It has two satellites. Man has sent many spaceships to Mars to look for signs of life there. Saturn: Saturn is almost as big as Jupiter. It has many huge rocks and ice rings. Saturn may have sixty moons, or more. Earth: The earth is the planet where human beings live. It has water and air. The earth is the only place where we have life at present. Besides, it has a satellite. Wang Xing: Uranus is blue-green and very cold. Uranus has many slender rings of ice and dust. It is known that it has twenty satellites, maybe more. Neptune: Neptune is a blue planet. It has many slender rings. Neptune has at least eight satellites.

Let me explain the stars again! Stars are spherical objects woven by hot gases. Stars themselves emit light and heat. They look small because they are too far away from us. The biggest star is much bigger than our biggest star, the sun. Stars always appear in the sky. As the earth rotates, the stars seem to move from east to west. The number of stars is countless! Scientists observe them through a tool called a telescope. Stars have different sizes and brightness, and some constancy looks bright, which may be because they are bigger or hotter than other stars around them, or because they are closer to the earth.

I must be a scientist in the future!

Chapter Four: Reflection on Earth Science.

The book Earth Science has four chapters and consists of fourteen lessons. What I like best is the third chapter "Weather on Earth" and my thinking on "Earth Science"-Chen Tailun. There are three lessons in this chapter: the first lesson is weather, and the second lesson is water cycle. The third lesson is to describe the weather. I like the first lesson because it says "the four layers of the earth still exist in the atmosphere". These four layers are troposphere, stratosphere, mesosphere and thermosphere. The troposphere is the closest layer to the earth, where clouds, rain, snow and lightning all occur. In the stratosphere, the air is not static. A strong wind called "Rapids" blew on this floor. The middle layer is located between the thermosphere and the advection layer. The thermosphere is the uppermost layer of the atmosphere, where an optical phenomenon called "aurora" will appear. I want to be a scientist when I grow up and help my country find more scientific treasures!

Chapter 5: Reflection on Earth Science.

Today, I read the knowledge of fossils and fuels in earth science and introduced how fossils were formed.
